What about the extinction ratio of the filter?

Hello. I'm not sure what you're referring to with the "extinction ratio" of the filter. If you are perhaps referring to the filter factor - i.e. the amount of f-stop exposure compensation when using the filter with a manual exposure camera or light meter - I believe for this particular filter that value is 1. Tiffen has a small section on Filter Factors you may find helpful here: http://www.tiffen.com/tiffen_edu_camera_filters.html Please let us know if there is anything else we can assist with.

I would expect that you would notice a reduction in glare, if you tune the orientation of the filter sheet. Be aware that there is an overall reduction of light through the sheet, even when it is not affecting the glare.

The filter has two sides: glossy and matte. The glossy side is quite reflective. The matte side is far less reflective, but does slightly increase the glare reflecting off my monitor. This is especially apparent when the background is black or a dark color. This is something that could be improved in future iterations. Still, as it reduces the harsh light emanating from the monitor, it is totally worth it!

Clear filter, 007M, is the prefered choice and priced higher. UV coating can slightly distort coloring and its benefits are debatable.

I believe the fish-eye filter merely gives you a fisheye-like distortion. The wideness of the view will depend entirely on the lens you use.

This particular technology is proprietary and the manufacturer doesn't give a number. In marine applications, a 10μ filter is usual for fuel-water separation.

Only my first filter was appreciably off-white after a year.Keep in mind that their main purpose is to avoid contaminating the RO membrane.

Agreed - Amazon doesn't do enough to describe the product. That said, the photo they supply is accurate, as the filters that come with it are the 0.6, 0.9, and the 1.2 neutral density filters. It was exactly what I was looking for and despite the lack of information, I'm very happy with the purchase. Hope that helps.

If you imagine filter as the shape of a "D" in the middle of the straight line there should be a small tab. It is the same blue material in the filter. Pull the tab and the filter should come out easily. If the tab isn't there for some reason just pull the filter up.

Certainly not for me, I could not justify the reduced light transmission of the APD filter. I use this often at f/1.2 and the APD version may be worse than f/1.4, some say 3/4 an f stop. Personally I thought about changing until I saw the impact on light and a rendering that i did not prefer.

Depends on the environment you are in. You can tell by how full the filters appear. That would be my guess.

this shouldn't interfere with any portion of focusing either in or out of focus regions. If you put this to its fullest setting you will be left with a very close to black out filter. What you will notice its that you will probably have areas off uneven filtering the darker you set the filter.

I'm assuming that it is dependent on the volume of water that passes through the filter. I haven't actually tested it.

Hello Sandy. Filters do a lot to the photographs. They eliminate the glare the sun causes, The haze the air shows sometimes, the greenish skin tones. They also protect the cameras lens from getting scratched.

I don't see it because it does not happen with the kind of photography I'm into. If you like using 8-10 stop ND filters to do long exposures in daylight, or like to open your aperture all the way and point directly at the sun, then you will have issues with it. It will not affect most users in normal practical situations.

The macro ability is almost too good. I was disapointed, for a while there, that it would not focus, at times, with a Polaroid and UV filters. I later realized that it would focus on any dust on the filter (especially when the sun is not in your back).

This filter reduces the amount of light hitting the sensor so allows you to increase the exposure time obtaining blurred moving subjects. e.g. Use it with a tripod to photograph the sea or rivers and streams like in this pic http://500px.com/photo/3539311.
